Description

A battery pole group assembly pressure test device

technical field

The utility model relates to the field of accumulator manufacturing, in particular to a test device capable of testing the assembly pressure of accumulator pole groups. the

Background technique

With the development of power lead-acid batteries, the uniformity and service life have become the focus of consumers and manufacturers. For the battery itself, the assembly pressure determines the life and uniformity of the battery. The assembly pressure should not only prevent the initial capacity of the battery from being affected by the loose assembly, but also prevent the ions from the electrochemical reaction from being able to pass through if the assembly is too tight, and it is also required that the assembly pressure can better withstand the effects caused by the expansion of the active material. Force, prevent the active material from falling off, and reduce the degree of stratification of the electrolyte. the

The battery assembly pressure test method in the prior art is to artificially feel the tightness of the assembly of the battery, and lacks a device that can quantitatively test the assembly pressure of the battery; only by manually sensing the assembly pressure is likely to cause the actual assembly of the battery to be too tight or too tight. The problem of looseness cannot fully meet the requirements of actual production for battery performance. the

Detailed ways

As shown in Figure 1, a battery assembly resistance testing device, including a test bench 8, the test bench 8 is provided with an upright support plate 9, a horizontal supporting plate 3, a pressing plate 4 opposite to the supporting plate 3 and a driving pressing plate 4 A cylinder 5 moving vertically, the driving end of the piston rod of the cylinder 5 is fixedly connected with the pressing plate 4 . Near the supporting plate 3, there is also a backing plate 7 for limiting the position of the battery, so as to prevent the assembly center from deviating from the center of the supporting plate 3 and the pressing plate 4, which will affect the accuracy of the test data. the

A control box 2 is also arranged on the test bench 8, and a display 6 and control buttons are arranged on the control box 2. A pressure sensor 1 is arranged at the bottom of the supporting plate 3, and the output signal of the pressure sensor 1 is input into the control box, and is displayed on the display 6 after processing. . the

The working principle of the above test device is as follows:

First place the battery tank on the supporting plate 3, and let it lean against the backing plate 7 at the same time to ensure that the centers of the supporting plate 3 and the battery tank coincide. Then put the pole group into the small chamber of the battery tank, press the control button, the piston rod of the cylinder 5 is extended, and the pressure plate 4 is driven to press the pole group into the battery tank. During this process, the pressure sensor 1 will detect the signal Real-time output to the control box 2. When the assembly is completed, the control box 2 finally displays the maximum pressure on the supporting plate 3; after the test is completed, press the control button, the piston rod of the cylinder 5 shrinks, and the pressure plate 4 returns to prepare for the next test. the
